Clutch Master Cylinder Kit Nissan E20 1800 1983- ( 15.87mm )

The Clutch Master Cylinder Kit for the Nissan E20 1800 (1983 and later models) is an essential repair and replacement kit designed to restore the clutch master cylinder to optimal performance. This kit is specifically engineered for use with the Nissan E20's hydraulic clutch system, featuring a 15.87mm bore diameter, ensuring compatibility and precise operation in vehicles with the 1800cc engine.

Kit Components:
The clutch master cylinder kit generally contains the following components to fully rebuild or repair the master cylinder:

Piston Assembly:
The piston, typically made of high-strength steel or aluminum, is precision-machined to move smoothly within the cylinder bore (15.87mm in diameter). This part is responsible for pushing hydraulic fluid from the master cylinder to the clutch slave cylinder when the clutch pedal is depressed.
The piston rod attaches to the clutch pedal via a clevis pin or other attachment mechanism, ensuring smooth movement and pressure transfer.

Rubber Seals (O-rings and Cup Seals):
Primary and Secondary Seals: These are made from durable EPDM rubber, designed to withstand high temperatures and constant exposure to brake fluid (DOT 3 or DOT 4). They ensure the piston operates smoothly while maintaining a tight, leak-proof seal inside the master cylinder.
Dust Boot: A rubber dust boot covers the external portion of the piston, protecting the internal components of the master cylinder from dust, dirt, and moisture that could cause wear or corrosion over time.

Return Spring:
The return spring ensures that the piston returns to its resting position after the clutch pedal is released. It is made from high-tension steel to withstand repeated use without losing elasticity.

Circlip and Retaining Components:
A circlip or similar retaining component keeps the piston and other internal parts securely in place within the cylinder. These components are usually made from stainless steel or another corrosion-resistant material.

Reservoir Seal:
A rubber seal for the master cylinder reservoir ensures that the hydraulic fluid remains sealed within the system, preventing leaks. It is designed to fit snugly at the junction between the fluid reservoir and the master cylinder body.

Bore Cleaning Components (Optional):
Some kits may include small brushes or cleaners designed to help clean the bore of the master cylinder before reassembling the new components.
Material & Construction:

High-Quality Rubber and Steel Components: The seals and gaskets are typically made from EPDM rubber to ensure they remain flexible and resistant to degradation, even after long-term exposure to hydraulic brake fluid. The piston and spring are made from hardened steel or aluminum, which are lightweight but strong enough to handle the high pressure required in the clutch system.

Bore Size (15.87mm):
The bore size of the master cylinder, 15.87mm, is a critical measurement for hydraulic pressure. This ensures the master cylinder kit components are perfectly sized to maintain consistent hydraulic pressure and smooth clutch operation.

Functionality:
The clutch master cylinder kit is designed to restore full hydraulic function to the master cylinder, ensuring that when the clutch pedal is pressed, the hydraulic fluid is forced through the system and into the slave cylinder.
The piston's movement is critical for maintaining the pressure required to operate the clutch efficiently, and the seals ensure the fluid remains inside the system without leaking.

Durability & Resistance:
Heat and Fluid Resistance: Since the hydraulic fluid heats up during operation, the seals and rubber components in the kit are formulated to resist high temperatures without losing their elasticity or effectiveness. This is essential for ensuring long-term performance without degradation.
Corrosion Resistance: The steel and aluminum components in the kit are treated or coated to resist corrosion, which is important because brake fluid can absorb moisture over time, leading to potential rusting or corrosion in untreated materials.

Installation:
Direct Fit: The components in the kit are designed as direct replacements for the worn parts in the original clutch master cylinder. No modifications are required if the kit is used in the Nissan E20 1800 models from 1983 onwards.
Simple Rebuild Process: Once the master cylinder is disassembled, the kit allows for a straightforward rebuild process. The seals, piston, and other components fit into the cylinder body with precision, restoring the master cylinder to factory-level performance.
Compatibility:
This clutch master cylinder kit is specifically designed for the Nissan E20 1800cc engine, manufactured from 1983 onwards, ensuring it fits the hydraulic clutch system of this vehicle model.

Application:
Restores Proper Clutch Operation: Over time, the seals inside the master cylinder can degrade, leading to fluid leaks and reduced hydraulic pressure. This kit restores the system's ability to build and maintain pressure, ensuring smooth and consistent clutch operation.
Maintenance:
Periodic Replacement: The clutch master cylinder seals and piston components will naturally wear out over time due to the repeated pressure cycles and exposure to hydraulic fluid. The clutch master cylinder kit provides all the necessary parts for replacing these components, extending the lifespan of the vehicle's clutch system.

The Clutch Master Cylinder Kit for Nissan E20 1800 (1983-onwards, 15.87mm bore) is a comprehensive set of components designed to restore the clutch master cylinder's functionality. Featuring a 15.87mm bore piston, high-quality EPDM rubber seals, a durable return spring, and protective dust boots, the kit ensures reliable performance by maintaining hydraulic pressure and preventing leaks. Built to the specifications of the Nissan E20 1800's clutch system, this kit is ideal for keeping the clutch system in top working condition, providing long-term reliability, and smooth clutch engagement.
